Acute cilio-choroidal effusion due to acetazolamide: unusual posterior involvement (OCT aspects)

Acetazolamide, a sulphonamide-derived medication, frequently used in glaucoma and after cataract surgery, can very rarely cause idiosyncratic reaction, and few reports are present in literature.1, 2, 3 We report ocular coherence tomography (OCT) scans of the posterior pole in a case of ciliary body oedema after the drug administration causing bilateral angle-closure glaucoma (ACG). In our case we found a massive choroidal effusion with posterior retinal folds and papillary oedema, never described before in literatur
